digit-display pressure gauge Application description MAT900 series digit-display pressure gauge is on-line measuring instruments control by single chip. It uses the battery long-term power supply, no external power supply, convenient installation and use This series of digit-display pressure gauge use to test of pressure gauge, absolute pressure, differential pressure, the form of variety, divided into common type and explosion-proof type, can meet a variety of measurement needs. It overcome the many fundamental shortcomings of pointer pressure gauge, such as low accuracy, poor reliability, high damage and so on. Particularly used in the corrosion, vibration and other places, even more of its outstanding performance. This product is qualification national metrology department, explosion-proof sector, has widely used in petroleum, chemical, power and other fields. Type instruction MAT900 is universal; applicable to non-explosion-proof place. MAT900B is intrinsically safety explosion-proof; apply to explosion-proof place. Product characteristics large screen: Large LCD screen display, reading visual clarity, adaptation to the wide environment temperature. high precision: advanced microprocessor technology, import monitoring chip, stable performance and high precision. low power: ultra-low-power intelligent control, battery continuous use two to three years. corrosion protection: overall stainless steel seal structure, adapt to corrosive medium environment. vibration: anti-vibration device processing, fastening assembly, normal use in vibration place. Technical reference measuring range: during -0.1--60MPa which sub-range can be selected, pressure unit MPa,KPa optional overvoltage limit: 2.5 times of full scale accuracy grade: 0.4, 0.5, 1.0 display accuracy: 4 bit(LCD) operating voltage: DC3V battery powered sampling time: factory setting 2.5 seconds / time(can be set as user’s requirements) applicable medium: the liquid, gas compatible with ceramic, stainless steel medium temperature: -40 85°C ambient temperature : -20 60°C -30 60°C mounting thread: M20×1.5(special installation user requirements) Selection table MATenterprise standard900digit-display pressure gauge Bexplosion-proof typepressure range1threaded connection M20*1.5(please specify other size thread)installation2flange connection DN20(please specify other size thread)3other special requirements
